Hardware/software co-verification is find out how to ensure that embedded process software program works effectively with the undefined, and that the has been adequately designed to run the software program effectively -before huge sums are spent on prototypes or production. this is often the 1st e-book to use this verification strategy to the swiftly starting to be box of embedded systems-on-a-chip(SoC). As conventional embedded approach layout evolves into single-chip layout, embedded engineers has to be armed with the mandatory info to make expert judgements approximately which instruments and technique to installation. SoC verification calls for a mixture of services from the disciplines of microprocessor and desktop structure, common sense layout and simulation, and C and meeting language embedded software program. earlier, the correct details on the way it all matches jointly has now not been to be had. Andrews, a well-known specialist, presents in-depth information regarding how co-verification rather works, easy methods to succeed utilizing it, and pitfalls to prevent. He illustrates those innovations utilizing concrete examples with the ARM middle - a know-how that has the dominant marketplace proportion in embedded process product layout. The significant other CD-ROM includes all resource code utilized in the layout examples, a searchable ebook model, and necessary layout instruments. * the single booklet on verification for systems-on-a-chip (SoC) out there* Will retailer engineers and their businesses time and cash via displaying them how you can accelerate the checking out technique, whereas nonetheless averting expensive errors* layout examples use the ARM middle, the dominant expertise in SoC, and the entire resource code is integrated at the accompanying CD-Rom, so engineers can simply use it of their personal designs

Veriﬁcation and Validation Two important concepts of integrating hardware and software are veriﬁcation and validation. These are the ﬁnal steps to ensure that a working system meets the design requirements. 16 Embedded System Veriﬁcation: An Introduction Veriﬁcation: Does It Work? Embedded system veriﬁcation refers to the tools and techniques used to verify that a system does not have hardware or software bugs. Software veriﬁcation aims to execute the software and observe its behavior, while hardware veriﬁcation involves making sure the hardware performs correctly in response to outside stimuli and the executing software.
When the prototypes were delivered and brought up in the lab, the manager of each group would pace back and forth trying to determine what worked and what was broken. What usually ended up happening was that the hardware engineer would tell his manager that there was something wrong with the software just to get the manager to go away. Most engineers prefer to be left alone during these critical project phases. There is nothing worse than a status meeting to report that your design is not working when you could be working to ﬁx the problems instead of explaining them.
Software engineers who wrote the application software struggled to ﬁgure out why the performance was so much lower since not much had changed in the application code. Hardware engineers tried to study the hardware behavior, but using logic analyzers that are better suited for triggering on errors than providing wide visibility over a long range of time, it was difﬁcult to even decide where to look. The RTOS vendor provided most of the system software and so there was little source code to study.
